The mighty beast looks just about ready to lose all the camo and reveal its muscular body.

Much like the Ford Focus RS, the highly-anticipated Mercedes-AMG E63 will have a drift mode to enable tail-happy cornering even though the car will come exclusively in an all-wheel drive flavor. But that’s obviously not actually going to be the highlight of Affalterbach’s next high-powered machine. The leaked spec sheet revealing some impressive numbers signals the arrival of a midsize sedan capable of delivering performance levels not too long ago found only on supercars.

It’s going to use the now familiar biturbo 4.0-liter V8 engine set to be offered with 563 hp (420 kW) & 553 lb-ft (750 Nm) in the regular E63 and with as much as 604 hp (450 kW) & 626 lb-ft (850 Nm) in the flagship E63 S model. The latter is going to complete the 0-62 mph (0-100 kph) run in only three and a half seconds en route to an electronically-capped 155 mph (250 kph).That being said, in some markets there’s going to be a less restrictive limiter allowing the E63 to hit at least 174 mph (280 kph) the outgoing model can do.

The 4MATIC setup will receive the V8’s muscle from an AMG Speedshift version of the company’s nine-speed automatic transmission and we also know the new E63 in the full-blown AMG specification will benefit from the C63 S Coupe’s electronically controlled rear differential.

Mercedes-AMG boss Tobias Moers has announced “the upcoming AMG E63 will make the biggest leap ever,” so this statement alone is reason enough to believe the new car is going to be an absolute rocket.

Insider sources have confirmed the Mercedes-AMG E63 Sedan will be introduced next month at the Los Angeles Auto Show. The wagon version pictured above should follow shortly and it might debut in March 2017 in Geneva.

Its arch rival from BMW M is expected to come out in the second half of next year also only with an automatic transmission, but with a choice of either a rear-wheel drive layout as usual or an xDrive setup for the first time in the M5’s history.
